Due to a bug in the software used to extract the surface brightness profiles (PYPROFFIT), the profile shown in red in Fig. 3 of the original paper is incorrect. The correct profile is presented in Fig. 1 here, which shows that the surface brightness drops by a factor of ∼10 at the position of the discontinuity (instead of the factor of ∼6–7 originally reported). This was the only profile presented in the original paper affected by the bug in PYPROFFIT.
